Kingdom Phylum Class Order Family
ANIMALIA ARTHROPODA INSECTA ODONATA GOMPHIDAE

Scientific Name: Epigomphus clavatus
Species Authority: Belle, 1980
Common Name(s):
English Guatemalan Knobtail

Assessment Information [top]

Red List Category & Criteria: Endangered B1ab(iii) ver 3.1
Year Published: 2009
Date Assessed: 2007-03-01
Assessor(s): Paulson, D. R.
Reviewer(s): Clausnitzer, V. & Kalkman, V. (Odonata Red List Authority)
Justification:
E. clavatus has an extent of occurrence is less than 1,000 km² and much of that area has already been deforested. The species is only known from two localities although there is much forested land in-between them. The continued deforestation of viable habitat is expected. The species is known only from the type description from the Guatemalan Petén and from an additional specimen reported by Enrique González from Lagunas de Montebello, Chiapas (D. R. Paulson pers. comm. 2008).
History:
2006 Endangered (IUCN 2006)
2006 Endangered
1996 Endangered
1994 Indeterminate (Groombridge 1994)
1990 Indeterminate (IUCN 1990)

Population [top]

Population: The population size of E. clavatus is not known.
Population Trend: Unknown

Habitat and Ecology [top]

Habitat and Ecology: E. clavatus is found at forest streams.
Systems: Terrestrial; Freshwater

Threats [top]

Major Threat(s): Deforestation of E. clavatus habitat is assumed to continue and much of its known range is already deforested.

Conservation Actions [top]

Conservation Actions: E. clavatus is not known to be present in any protected area. Searches for other populations are urgently needed, as is the extent of habitat (forested streams) available in the general area. Population size and trends have to be monitored. Realistically, there is no odonatologist living anywhere near its known range.
